Vulnerability from csaf_redhat - Published: 2013-03-05 20:56 - Updated: 2026-01-28 22:34Summary
Red Hat Security Advisory: openstack-keystone security, bug fix, and enhancement update
Severity
Moderate
Notes
Topic: Updated openstack-keystone packages that fix multiple security issues,
various bugs, and add enhancements are now available for Red Hat OpenStack
Folsom.
The Red Hat Security Response Team has rated this update as having moderate
security impact. Common Vulnerability Scoring System (CVSS) base scores,
which give detailed severity ratings, are available for each vulnerability
from the CVE links in the References section.
Details: The openstack-keystone packages provide Keystone, a Python implementation
of the OpenStack identity service API, which provides Identity, Token,
Catalog, and Policy services.
The openstack-keystone packages have been upgraded to upstream version
2012.2.3, which provides a number of bug fixes and enhancements over the
previous version. (BZ#908995)
This update also fixes the following security issues:
It was found that Keystone failed to properly validate disabled user
accounts, or user accounts associated with disabled tenants or domains,
when Amazon Elastic Compute Cloud (Amazon EC2) style credentials
(credentials that are issued in the same format as standard Amazon EC2
credentials) were in use. Such users could use this flaw to access
resources they should no longer have access to. (CVE-2013-0282)
A denial of service flaw was found in the Extensible Markup Language (XML)
parser used by Keystone. If a malicious XML file were uploaded for
processing, it could possibly cause Keystone to consume an excessive amount
of CPU and memory. (CVE-2013-1664)
A flaw was found in the XML parser used by Keystone. If a malicious XML
file were uploaded for processing, it could cause Keystone to connect to
external entities, causing a large amount of system load, or allow an
attacker to read files on the Keystone server that are accessible to the
user running the Keystone service. (CVE-2013-1665)
Red Hat would like to thank the OpenStack project for reporting these
issues. Upstream acknowledges Nathanael Burton (National Security Agency)
as the original reporter of CVE-2013-0282.
All users of openstack-keystone are advised to upgrade to these updated
packages, which correct these issues and add these enhancements. After
installing the updated packages, the Keystone service (openstack-keystone)
will be restarted automatically.

Vulnerability from csaf_redhat - Published: 2013-03-05 20:56 - Updated: 2024-11-22 06:15Summary
Red Hat Security Advisory: openstack-keystone security, bug fix, and enhancement update
Severity
Moderate
Notes
Topic: Updated openstack-keystone packages that fix multiple security issues,
various bugs, and add enhancements are now available for Red Hat OpenStack
Folsom.
The Red Hat Security Response Team has rated this update as having moderate
security impact. Common Vulnerability Scoring System (CVSS) base scores,
which give detailed severity ratings, are available for each vulnerability
from the CVE links in the References section.
Details: The openstack-keystone packages provide Keystone, a Python implementation
of the OpenStack identity service API, which provides Identity, Token,
Catalog, and Policy services.
The openstack-keystone packages have been upgraded to upstream version
2012.2.3, which provides a number of bug fixes and enhancements over the
previous version. (BZ#908995)
This update also fixes the following security issues:
It was found that Keystone failed to properly validate disabled user
accounts, or user accounts associated with disabled tenants or domains,
when Amazon Elastic Compute Cloud (Amazon EC2) style credentials
(credentials that are issued in the same format as standard Amazon EC2
credentials) were in use. Such users could use this flaw to access
resources they should no longer have access to. (CVE-2013-0282)
A denial of service flaw was found in the Extensible Markup Language (XML)
parser used by Keystone. If a malicious XML file were uploaded for
processing, it could possibly cause Keystone to consume an excessive amount
of CPU and memory. (CVE-2013-1664)
A flaw was found in the XML parser used by Keystone. If a malicious XML
file were uploaded for processing, it could cause Keystone to connect to
external entities, causing a large amount of system load, or allow an
attacker to read files on the Keystone server that are accessible to the
user running the Keystone service. (CVE-2013-1665)
Red Hat would like to thank the OpenStack project for reporting these
issues. Upstream acknowledges Nathanael Burton (National Security Agency)
as the original reporter of CVE-2013-0282.
All users of openstack-keystone are advised to upgrade to these updated
packages, which correct these issues and add these enhancements. After
installing the updated packages, the Keystone service (openstack-keystone)
will be restarted automatically.

OpenStack Keystone Grizzly before 2013.1, Folsom 2012.1.3 and earlier, and Essex does not properly check if the (1) user, (2) tenant, or (3) domain is enabled when using EC2-style authentication, which allows context-dependent attackers to bypass access restrictions.

"text": "The openstack-keystone packages provide Keystone, a Python implementation\nof the OpenStack identity service API, which provides Identity, Token,\nCatalog, and Policy services.\n\nThe openstack-keystone packages have been upgraded to upstream version\n2012.2.3, which provides a number of bug fixes and enhancements over the\nprevious version. (BZ#908995)\n\nThis update also fixes the following security issues:\n\nIt was found that Keystone failed to properly validate disabled user\naccounts, or user accounts associated with disabled tenants or domains,\nwhen Amazon Elastic Compute Cloud (Amazon EC2) style credentials\n(credentials that are issued in the same format as standard Amazon EC2\ncredentials) were in use. Such users could use this flaw to access\nresources they should no longer have access to. (CVE-2013-0282)\n\nA denial of service flaw was found in the Extensible Markup Language (XML)\nparser used by Keystone. If a malicious XML file were uploaded for\nprocessing, it could possibly cause Keystone to consume an excessive amount\nof CPU and memory. (CVE-2013-1664)\n\nA flaw was found in the XML parser used by Keystone. If a malicious XML\nfile were uploaded for processing, it could cause Keystone to connect to\nexternal entities, causing a large amount of system load, or allow an\nattacker to read files on the Keystone server that are accessible to the\nuser running the Keystone service. (CVE-2013-1665)\n\nRed Hat would like to thank the OpenStack project for reporting these\nissues. Upstream acknowledges Nathanael Burton (National Security Agency)\nas the original reporter of CVE-2013-0282.\n\nAll users of openstack-keystone are advised to upgrade to these updated\npackages, which correct these issues and add these enhancements. After\ninstalling the updated packages, the Keystone service (openstack-keystone)\nwill be restarted automatically.",
